This module is simply-written and provides fast audio data extraction for PCM wav files.
Though the module claims to be incomplete, due to its inability to process a few rarely-used proprietary formats, it's definitely well-written to process the formats it does support.
I've been using this module to perform audio extraction for a scientific audio processing and aggregation and it hasn't failed me yet. The only reason I would have to replace its functionality is to process more types of audio data.
The only complaint I have is that the sample values it returns are in short-integer format, which I have to convert into floating-point values in order to process them.
